## Questions

### Who runs investment decisions at Operator Stack?

Investment decisions are made by two unnamed co-founders and general partners who previously served as Chief Product Officer at Uber Freight and CTO of SumUp North America, alongside a third general partner who was Head of Corporate Development at Yelp. The three GPs collectively represent over 40 years of product, technology, and business development experience, per the firm’s website.

### How does Operator Stack source proprietary deal flow?

The firm sources deal flow through its network of 200 operator LPs, who are active technology executives and founders across logistics, fintech, and enterprise software. These operators often encounter early-stage companies solving problems they recognize firsthand, creating a sourcing channel rooted in practitioner networks rather than traditional GP outreach.

### Which sectors does Operator Stack explicitly avoid?

Operator Stack defines a clear positive mandate around Logistics/Supply Chain, FinTech, and B2B SaaS, and its principals' operating experience is concentrated in those domains. No exclusion list is published, but sectors such as digital health, climate tech, or deep science fall outside the stated focus, making investment in those areas unlikely.

### Where does the operating experience of the Operator Stack team come from?

Operating experience is rooted in the three GPs’ tenures at Uber Freight, Fivestars, Yelp, Cota Capital, and Capital One Ventures. The co-founding GP from Uber Freight helped scale that business to $6B in bookings, while the other co-founding GP built Fivestars’ payments infrastructure and led its $317M exit to SumUp, per the firm’s own disclosures.
